Customer Questions & Answers

Can I purchase a chimney cap if my flue doesn't extend beyond the chimney cap?

Asked by: Joe
The directions for the Master Flow brand include an optional kit that has 'legs' that attach to the inside of the chimney flue. So I would say yes. See the installation guide here:

9 in. x 9 in. Adjustable Single Flue Stainless Steel Chimney Cap is rated 3.0 out of 5 by 3.
Rated 5 out of 5 by from NEW CHIMNEY CAP This cap was a excellent fit and well made. Faster then normal shipping.

Rated 2 out of 5 by from Good quality but... The cap was delivered on time to my door step. I installed it Ok. It is well made and looks like it is made of stainless steel. It is sturdy/rugged and should last a long while. It fit very well over my liner/flue square pipe. My only regret is that is does not measure 16" by 16". The cap measures about 12 inches wide/square and does not completely shield my chimney outer structure from rain since my Chimney outer bricks measure 16" by 16". The website specification says it is supposed to be 16" by 16". It measures ~12" x 12".

Rated 2 out of 5 by from Average product Though the overall construction of this product was solid, it lacked some important features. The lid and openings on the side are very small as compared to the Master Flow Cap. The small openings on this cap can be hazardous as enough free air space does not exist. The cost of this cap is also much more than the Master Flow. The side attachment does not work as well as the Master Flow. I would not buy Chim Cap again.
